Researchers affiliated with Harvard Business School recently conducted a decade-long longitudinal study on retirement behavior—tracking 14 individuals closely over ten years and surveying 106 more—revealing comparative insights into different retirement transition approaches.
Their findings, published in the 2024 Harvard Business Review article Retirement Without Regrets, present contrasting case studies, map common phases of retirement transition, and highlight behavioral frameworks retirees have used to increase their retirement success. A key takeaway: retirees often struggle when their vision of happiness is unclear or lacks purpose.
Charting a course for retirement is difficult without a clear destination. The study illustrates this by contrasting two knowledge workers’ post-career lives—one who proactively envisioned a fulfilling retirement found happiness quickly, while the other became isolated and unhappy. Think of two people embarking on separate open-road adventures; the one with a map will likely enjoy a more efficient trajectory.
Building on this, another study, titled Back to the Present: How the Direction of Mental Time Travel Affects Similarity and Saving, explores deliberate foresight. Led by Katherine Christensen, assistant marketing professor at Indiana University, the research asked whether feeling a stronger connection to one’s future self would encourage more retirement saving. After 20 experiments, the answer was a clear yes.
The potentially game-changing retirement research found that more than 80% of the time, individuals imagining their future start by thinking about the present. Leveraging this, Christensen and her team flipped the typical mindset—by asking participants where they wanted to end up instead of where they were or how they would get there, they helped people overcome natural cognitive biases and adopt more productive saving behaviors.
The 14% Difference
Time in the market typically beats attempts to time market fluctuations. Therefore, long-term planning can play a crucial role in unlocking the financial flexibility that helps to allow retirees to sleep well at night, free from the fear of depleting their nest egg.
In one experiment analyzing over 6,700 customers of a Swedish fintech company, individuals with low-balance savings accounts were 14% more likely to invest in a long-term savings product when prompted to think about their future selves first. The simple prompt used was: “The year is 2034… rewind back to 2024 and consider saving for 2034 you,” according to contributing author Hal Hershfield.
This straightforward mental technique might give future retirees a measurable edge with real financial impact. If they simply take the time to fully imagine their future retirement before mentally rewinding to the present, they may increase their chances of making more effective long-term investment decisions. Revisiting the open-road journey parallel: setting the GPS ahead of time improves the odds of arriving on schedule—and spotting roadblocks before they hit.
The Return Trip Effect
The return trip effect—the feeling that the journey home is shorter than the journey out—is often attributed to the way uncertainty stretches our perception of time. Christensen and colleagues suggest this cognitive quirk applies not just to miles but to years—shaping how people perceive the future and, critically, how they relate to retirement savings.
Taking time for self-reflection can help individuals envision a future life beyond their primary working years, transforming retirement from a distant, abstract destination into a familiar stop on life’s journey.
The exercise begins by vividly imagining retirement: “What is life like? Where do I live? How do I spend my days?” Once that vision crystallizes, individuals mentally rewind to the present and ask, “What small step can I take right now to increase the probability of that future?” Practiced consistently, this exercise helps clear the fog of retirement uncertainty, creating a mental framework that drives action today in service of the life envisioned tomorrow.
Bottom Line
Future obligations rarely spark the same urgency as today’s immediate needs and desires. It’s all too easy to put saving off until another day, as instant gratification often wins out over long-term planning. Rather than battling human nature head-on, the Back to the Present study reveals that with discipline and mindfulness, individuals can tangibly connect with their future selves—transforming retirement planning from conceptual to constructive.
Whether viewed as a life hack, a mental technique, or a form of introspection, the driving idea of this cognitive time travel is clear: Retirement isn’t just about growing a bank account. It’s about buying the opportunity for peace of mind. The sooner a current or future retiree envisions their ideal life, the easier it becomes to take the first step toward building it. When practiced with consistency and intention, this exercise may help convert today’s modest savings into tomorrow’s purpose-filled retirement.
